I’ve also now created a public darcs repository on patch-tag that holds the CHP code:

darcs get http://patch-tag.com/r/twistedsquare/chp

While I’m tidying things up: I wired up the blog to a twitter account a while ago and then never told anyone about it. If you want to follow the blog through twitter (I don’t yet use the account for much more than that), you can do so.
